There has been odd occasions I had search difficulties, limited results. If the above process did not work, I restarted LPE. I do recall one or two occasions rebooting the router (leaving it off for a minute) and the computer to get a fresh ip and refresh ram. These all worked.

Also, if you see any version of LW 5.0 or 5.1 in your connection list, get them off. 5.1.2 in particular.
